I think Ryan is dying.......
Maybe, he has basically sacrificed his health for Lucaon and Christophe and no longer works as a hunter. Therefore he appears to be retired. It could also explain why he is being sentimental with Sihan and trying to get some recognition as being his father figure, as well as "letting go" by having fun drinking and eating junk food with Logan, which isn't something you really see any of the royals doing.
Also I think Logan is the spy
I also think that there's some off aura around Logan from the first time I saw him when he was working in Lucaon's Mansion and then show up again from Nowhere! ! (￣∇￣") also I don't actually want Ryan to die.. ? I mean yeah I So hated hime when he did that to Kyon but he was just worried about Lucaon So yeah .... I don't want him to go ..
"Sihan call me Dad " ok… I So didn't expect that (⊙…⊙ ) btw YES they found that asshole Edwin's place !!! (๑•ㅂ•)و✧ Now kick his ass and Save Master!! Also I love Cecilia she's cute and I kinda see her as trustworthy (▰˘◡˘▰)
